OBADIAII SEELY, OF SYRAOUSE, NEV YORK.

SPRINGva HINGE.

SPECIFICATION forming part of Letters Patent o. 438,115, dated October 7, 1890. Application led November 16, 1888. Serial No. 291,011. (Modell) To all whom it may concern:

Be it known that I, OBADIAH SEELY, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful Impi'ovements in Hinges, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure I vis a top plan or face View of the hinge. Fig. II is a vertical sectional elevation thereof, showing the construction of the pintles and the ears upon the leaves and the tension-lock. Fig. III is an end elevation showing the lock in the outer ear. Fig. IV is a like View with the lock in inner ear. Fig. V is an elevation of a pintle detached.

My invention relates to spring-hinges for doors, and to that class in which a coil is mounted substantially upon the central vertical line of the hinge, and upon which a torsion tension is produced by the opening of the door to which the hinge is attached, the torsion being su 'icient to close the door again.

The object of my invention is to produce a spring-hinge in which the spring occupies substantially the position of the ordinary pintle-bearing in a hinge, and which is connected to tension-adjusting devices or pins, which also operate as the pintles of the hinge.

My invention consists in the several novel features of construction and operation hereinafter described, and which are specifically set forth in the several clauses of claim hereto annexed.

It is constructed as follows: The hinge consists of the leaves l and 2, which may be of any form or of any style of ornamentation, each leaf being provided with ears 3, 4, 7, and 8, standing at right angles to the plane of the leaves and of the pintles 5 and 6. The ears 3 and el stand upon the leaf l, and 7 and 8 upon the leaf 2. The pintle 5 passes through the ears 7 and 3, and the pintle 6 through ears 4 and 8. All of the ears are perforated to receive the pintle, and, as shown in the drawings, the perforations through the ears 4 and 7 are circular and the perforations: through the ears 3 and 8 are hexagonal, though they may be of any other angular form. The pintles are substantially alike in construction.

The pintle 6 consists of a cylindrical stem having an angular periphery 10 fitting the angular ear-perforations and acircular bear ing 9, a head 1l, and a stem 12, and the head 1l is also grooved in the edge, as at 13, to receive the end of the spring rod or wire and hold it. In the drawings I show the pintle 5 as slightly differing in the detailed construction in that in 5 the angular portion 10 is next to the head 1l, and in the ends of the pintles I make the screw-driver slots 14.

It will be observed, first, that this hinge is capable of being used for either a right or a left hand hinge; second, that when I desire to adjust or impart tension to the spring I, for instance, insert the screwdriver into the slot in the pintle 5, push the whole pintle inwardly until the angular portion 10 is inside of the ear 3, and I then, holding the pintle in that position, turn the pintle around, twisting the coil of the spring B, which is mounted between the pintles, until I get the desired tension, and by twisting the pintle to the right the door will swing to the left through the spring action, and, third, that the tension can be adjusted by operating either pintle.

What I claim as my invention, and desire to secure by Letters Patent, is-` In a spring-hinge, the combination of the leaves l 2, provided, respectively, with ears 3 t and 7 8 adjacent to their ends, the ears 4 and '7 being provided with circular pintleholes and the ears 3 and 8 with angular pintle-holes, pintles provided with circular bearings iitting the circular ear-holes, and angular bearings fitting the angular ear-holes of said ears, and a spring inserted between. the pintles and held in place thereby, substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand this 10th day of November, 1888.

OBADIAI-I SEELY.

In presence of- HOWARD P. DENIsoN, C. W. SMITH.
